How to optimize a WordPress website using plugins.

WordPress is a very popular CMS used for creating websites. However, WordPress sites can be slow, which can harm conversions and search engine rankings. This article explores the most frequent performance issues with WordPress sites and offers some solutions.

To speed up your WordPress site you need to streamline everything: plugins, server, themes, content, etc. The idea is to minimize the use of plugins and external resources and use as much native WordPress functionality as possible.

Multiple plugins can slow down WordPress sites. Remove unused plugins and replace old ones with the latest versions (good for security as well). Ideally, replicate the plugin functionality you want in native WordPress code or custom PHP. The fewer plugins you use on your site, the less chance there is of performance and upgrade issues. Plugins can also call external resources, which introduce uncertain delays by relying on external servers.

Let’s see how to optimize the WordPress website with Plugins.

In this article, we are going to use a couple of plugins that will help a WordPress website load faster.

  3. Since W3 Total Cache will turn on all its caching features, there are a few that may not apply to you. The common ones are a CDN and the CloudFlare feature. Uncheck “Enable” on these features if you don’t have them.

Under Minify section check the Box to Enable and Select the Auto option.

  1. On the next step, on the sidebar, click on the Minify sub-section. Under HTML & XML, check Enable in the HTML minify settings. You can also check the other options, but make sure to test your site to see if it breaks.

Check enable, inline CSS minifiaction, inline JS minification, and line break removal.

  1. There are no options for this plugin and nothing to set up!

  1. In the newer version of WP Smush, there is a Bulk Smush feature that can smush all of your uploaded images. It has worked for us on smaller media libraries and it is very convenient, however, it is experimental (we’ve experienced some errors with it on larger media libraries). Have a look at the feedback forums if you are looking for support.

  1. That’s it! You’re finished.
